SPECIFICATION forming part of Letters Patent No. 662,745, dated November2'7, 1900.

Application filed April 12, 1900. Serial No. 12,544. (No model.)

To rtZZ whom it may concern:

Be it known that we, ALFRED THOMPSON and CARL THOMPSON, citizens of theUnited States, and residents of Fort Ransom, in the county of Ransomand'State of North Dakota, have invented a new and Improved DeviceforPreventing Horses from Cribbing, of which the following is a full,clear, and exact description.

This invention relates to improvements in devices for preventingcribbing of horses; and

the objectisto provideamangerattachmentso constructed that it cannot bereadily grasped and held by the teeth of a horse, that is at all timesfree to rotate, and in which there is no danger of clogging by feed orthe like.

We will describe a device to prevent horses from cribbing embodying ourinvention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a perspective view of a stall and manger, showing anattachment embodying our invention. Fig. 2 is a longitudinal section ofthe device. Fig. 3 is a cross-section of the device on the linear: a: ofFig. 1. Fig. 4 is a perspective view of a portion of one of thesupportingbars employed, and Fig. 5 is a perspective view of abearing-plate employed.

The device comprises a rotary part 1, which is preferably made oval incross-section, or substantially so. As here shown, it consists of tworods or bars 2 3, spaced apart, and around these rods or bars is placeda casing I, of suitable metal. The rods or bars are connected at theirends to bearing-plates 5, the said bearing-plates 5 being provided attheir inner sides with projections 6 for engaging in recesses 7, formedin the ends of the bars, and to prevent any possible rotation of thebars relatively to the plates the bars are provided with channels 8 atthe ends to re ceive the plates. The bars may be secured to the platesby any suitable means. We have, however, here shown screws 9 for thispurpose. On the plates 5 are lugs 10, which have bearings in bosses 11on plates 12, secured to the side walls of the stall in such position asto support the rotary part slightly above the 'front board of themanger, as indicated in Fig. l. Cylindrical devices for this purposehave heretofore been employed; but they are objectionable because theyare readily grasped and held by the teeth of a horse. In the presentdevice should a horse bite upon the rotary part it will be immediatelyturned or rotated, thus causing the horse to release his hold, and wehave found in practice that it is an absolute preventive againstcribbing, while in time it will eifect a perfect cure of the habit.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- 1. A device to prevent horses from cribbing,comprising a rotary part arranged above and extending along the frontboard of a manger, the said rotary part being substantially oval incross-section, substantially as specified.

2. A device for preventing cribbing of horses, consisting of a rotarypart, comprising two bars spaced apart, plates to which the ends of saidbars are connected, a metal sheathing extended over thebars,'bearinglugs on the plates, and sockets or bearings for receivingsaid lugs, substantiallyas specified.

3. A device for preventing cribbing of horses, comprising two barsspaced apart and having recesses and channels at their ends,bearing-plates having lugs on the inner sides to engage in the recessesformed in the ends of the bars while the plates are seated in thechannels, bearing-lugs on the outer sides of said plates, and platesadapted to be attached to the sides of a stall and to receive thebearing-lugs on the first-named plates, substan tially as specified.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.

ALFRED THOMPSON.
